Summary
Sandhills Wireless, LLC
isp legacy
SHWISP is Sandhills Wireless, LLC, a fixed-wireless broadband provider based at 105 W 2nd Street in Valentine, Nebraska, serving the sparsely populated Sandhills region of north-central Nebraska. The handle is literally the company's domain, shwisp.net.
What it's used for
- Rural fixed-wireless internet access. The AS announces one prefix,
162.221.132.0/22— 1,024 addresses — registered in ARIN to Sandhills Wireless itself. One aggregate, one registrant, one RIR: an entirely first-party inventory. - A
/22is the whole network. That is a realistic subscriber pool for a WISP covering a handful of ZIP codes in one of the emptiest parts of the United States, where the customer count is measured in hundreds rather than thousands. - Reverse DNS on one sampled address resolves to
www.shwisp.net, the company's own site, so the operator plainly uses the space itself.
Notable
- A single observed neighbour. WISPs in this position typically buy one transit circuit and hold portable address space so they can change providers without renumbering their customers — that, rather than resilience, is usually why a network this small runs BGP at all.
- Another sampled address wears an
echeloninternet.comhostname, a name not obviously Sandhills'. Reverse DNS shows what space carries, never who holds it, and a single PTR is far too little to build a story on — it is noted here only so a reader who sees it is not surprised by it.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,849 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
